ABSTRACT:
A circuit breaker for high-speed current-limiting breaking of a three-phase current in the event of a short-circuit condition. The breaker has three pairs of fixed and movable contactors, the latter being arranged for pivoting movement on a common shaft. The center movable contactor is biased against an opposing holder, such that in the event of a short-circuit, the bias is overcome and the movable contactors separate in unison from the fixed contactors.
